Dumb Question.
My race car is handicapped by fenders and doors, dont hold that against me because but my first love is a sprint car.
I've noticed several pictures of sprint cars with the front shocks mounted 1 upside down on the LF and 1 right side up on the RF. On my stockcar I mount both upside down for unsprung weight reasons. Why are the sprintcars doing it differently ? Just an interested observer.

Only speculation here...

Perhaps the race team(s) needed a certain valving for the shock on the RF? They could achieve it by turning the shock opposite way or by having it "right side up". There really isn't an upside down or right side up when it comes to shock absorbers.

You are correct to point out that most teams want the cartridge up to lessen unsprung weight.

if a shock is a 7 compression and a 2 rebound it wont matter how its mounted on the car it will always be a 7 comp/2 reb.

Any shock at any angle is going to dyno out the exact same everytime. however, I have heard this and its usually someone at a snowmobile shop tryin to sell the latest trick for some clowns sled...

the reason you would run a shock body down is simple and basic if you stop an think about it. rocks....... some places have nasty rocks that pit the shaft causing leaks and blown shocks. believe it or not it does help some. I prefer to go to places that are clay however.

I can't believe I wrote this!
2nd2none is correct. The valving stays the same irregardless of shock position.

That will teach me not to post at 6:am in the morning!!

Nope, we are going a different route. Something more affordable and local. Whiskey Lake Raceway, near Junction City, Kansas is starting an IMCA sprint class that will "tour" within the region.

Years ago, NRCA had the opportunity to align their 360 class with rules similar to ASCS. This would allow racers to "float" between ASCS and their home track or sanctioning body. This works very well with clubs in Nebraska, Missouri, Oklahoma, Colorado, etc. NCRA chose to stay with 23 degree factory iron heads and an odd-ball 20 square foot wing. Then in 2003, NCRA allowed ANY 23 degree iron head...factory or aftermarket. Now for 2005, NCRA is allowing a 25 square foot wing and ASCS aluminum heads but requiring those cars to add 75 pounds.

My biggest complaint is NO TECHNICAL OR SAFETY INSPECTION. NCRA has no inspectors and shows up at the track with just a few members of their organization. I suspect that some teams were using parts or modifications not legal for use.

I believe the 4+ Covenant Race Team will race IMCA for 2005 and a few other shows if they are close by.
